  • A. Terra satellite
    Terra is a flagship NASA Earth observation satellite that carries multiple instruments to monitor the planet’s climate, land, oceans, and atmosphere from polar orbit.
  • B. Landsat satellites
    Landsat satellites are a series of Earth-observing spacecraft that provide long-term, continuous multispectral imagery used worldwide for environmental monitoring, land-use mapping, and resource management.
  • C. Vanguard 1 satellite
    Vanguard 1 satellite is an early American artificial Earth satellite launched in 1958 that became the fourth human-made object in space and the oldest still in orbit, used primarily for geophysical and atmospheric research.
  • D. Landsat 9
    Landsat 9 is a NASA and USGS Earth observation satellite that continues the decades-long Landsat program by collecting high-resolution multispectral imagery to monitor and study changes on the planet’s surface.
  • E. Lunar Orbiter program
